Which of the following defines the wavelength of a wave? A. the distance between peaks of a wave B. the speed that a wave is passed from particle to particle C. the loudness of waves that travel through the air D. the height of a wave between peak and trough

My answer to the question is wavelength is the distance between two successful cress or successful troughs of a wave. which will be option A.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
